I am having a lot of difficulty for some reason when trying to customize the Category List Page conlib. I created the new ascx and ascx.cs files with the following in them. After a lot of work with it still not working, I tried to copy over the Category Details Page files and customize those to show the data I need, but it still does not function properly. To clarify, I need the products/links/webpages to display together in the sort order specified in the admin if possible. If it is not, then I guess I can settle for having them show up in their own repeaters.
If the category has no links or webpages in them, then the page loads and displays properly showing the products as intended.
If the category has links or webpages in them, then it goes to the general order page and shows the following on the frontend:
